[0021] The technical solution of the present invention will be further specifically described below through embodiments in conjunction with the accompanying drawings.

[0022] A locking device for circuit board processing, including a base 1:

[0023] A cross bar 2 is arranged on the front side of the top of the base 1, a limiting mechanism 3 is arranged on the cross bar 2, and a separating mechanism 4 and a locking mechanism 5 are successively arranged on the base behind the limiting mechanism 3;

[0024] The limiting mechanism 3 includes L-shaped plates 31 arranged at both ends of the rear side of the cross bar 2. A sliding seat 33 passing through a sliding opening 32 on the cross bar 2 is arranged on one side of the L-shaped plate 31, and a positive and negative lead screw 34 located on the front side of the cross bar 2 is arranged on the two groups of sliding seats 33. A convex seat 35 for fixing the end of the positive and negative lead screw 34 by a bearing is arranged on the top of the base 1;

[0025] The separating mechanism 4 includes a groove 41 for accommodating an air bag 42 arranged on the top of the base 1, and the air bag 42 is connected to an air tank through a pipeline;

[0026] The locking mechanism 5 includes two groups of strip-shaped openings 51 arranged longitudinally on the base 1. A locking plate 52 vertically intersecting the strip-shaped openings 51 is arranged on the top of the base 1. A U-shaped rod 53 is arranged at the bottom of the base 1. Both ends of the U-shaped rod 53 pass through the corresponding strip-shaped openings 51 and are connected to the locking plate 52. The front side of the U-shaped rod 53 is connected to an installation seat 54 at the bottom of the base 1 through a spring 55. An electric push rod 56 is arranged at the bottom of the base 1 in front of the U-shaped rod 53, and a push block 57 abutted against the U-shaped rod 53 is arranged on the output shaft of the electric push rod 56.

[0027] In this embodiment, an arc-shaped groove 6 is arranged on the top end surface of the base 1 between the limiting mechanism 3 and the locking mechanism 5, and the arc-shaped groove 6 is connected to a vacuum pump through a pipeline. When the circuit board is placed on the base 1 and fixed by the limiting mechanism 3 and the locking mechanism 5, the vacuum pump can further adsorb and fix the circuit board on the base 1 by evacuating the arc-shaped groove 6 to prevent the circuit board from falling off.

[0028] As Figure 2 shown, a cross bar 7 passing through a through hole on the sliding seat 33 is arranged in the sliding opening 32.

[0029] In this embodiment, a driving part 8 is arranged at the middle of the positive and negative lead screw 34, and a threaded hole screwed with the positive and negative lead screw 34 is arranged on the sliding seat 33.

[0030] In this embodiment, scale values are arranged on the surface of the cross bar 2. The adjustment range of the L-shaped plate 31 can be conveniently known through the scale values.

[0031] As Figure 3As shown, a limiting rod 9 is provided on the U-shaped rod 53 and passes through the round hole on the mounting seat 54. When the U-shaped rod 53 moves, it will drive the limiting rod 9 to slide in the round hole to prevent the U-shaped rod 53 from skewing when moving back and forth.

[0032] The usage method of the present invention: Adjust the distance between the two groups of L-shaped plates 31 according to the length of the circuit board in the processing batch. Among them, by rotating the positive and negative lead screw 34 to rotate it in the threaded hole of the sliding seat 33, and then driving the sliding seat 33 to slide in the sliding opening 32 while driving the L-shaped plate 31 to displace, so as to expand or reduce the distance between the two groups of L-shaped plates 31 to meet the production requirements. Then, the electric push rod 56 works to drive the push block 57 to squeeze the U-shaped rod 53 to move backward. When the U-shaped rod 53 slides backward in the strip-shaped opening 51, it drives the locking plate 52 to move backward to expand the distance between the locking plate 52 and the limiting mechanism 3. At the same time, the U-shaped rod 53 stretches the spring 55 to make it stretch;

[0033] At this time, people can conveniently embed the front end of the circuit board between the two groups of L-shaped plates 31 to fix it left and right. At the same time, the electric push rod 56 resets. Then, under the loss of the extrusion effect of the electric push rod 56, the spring 55 contracts and pulls the U-shaped rod 53 to move forward. While the U-shaped rod slides in the strip-shaped opening 51, it drives the locking plate 52 to move forward to lock and fix the circuit board on the limiting mechanism 3. Then, the vacuum pump can further adsorb and fix the circuit board on the base 1 by evacuating the arc-shaped groove 6. Finally, it realizes locking and fixing circuit boards of different specifications and sizes on the base 1 for processing work through the adjustable limiting mechanism 3, the adjustable locking mechanism 5, and the vacuum pumping of the arc-shaped groove 6;

[0034] After the processing is completed, the electric push rod 56 pushes the U-shaped rod 53 and the locking plate 52 to move backward. After the locking plate 52 is separated from the rear end of the circuit board, the airbag 42 can be inflated to make it stretch and slowly slide out of the groove 41, so as to lift the circuit board between the two groups of L-shaped plates 31 into the air or make it tilt, so as to facilitate people to pick up the circuit board at this time and remove it from the base 1, preventing the circuit board from adhering to the base 1 and making it difficult for people to find the picking part and resulting in difficulty in removing the circuit board.

[0035] The above has described the present invention in detail, but the content described is only the preferred embodiment of the present invention and cannot be considered as used to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
